Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial i+1m field J] The present invention relates to a master/satellite UPOS system used in mass retail stores such as supermarkets.

[Prior Art] Conventionally, each product has a product data file in which corresponding product data such as the unit price of the product and 5 product names is set corresponding to the code of the product, and the code of the product to be sold is entered through an input unit such as a keyboard. is input, the product data corresponding to the input code is read from the product data file to obtain sales data such as sales points, sales amount, etc., and this sales data is registered in the cumulative memory for each code. A POS system in which machines are connected via an inline line, one of them is set as a master machine, and cumulative sales data registered and processed in the cumulative memory of each other satellite machine is collected via the inline line. There is. In such a POS system, if the master machine collects the cumulative sales data of each satellite machine and collects the cumulative sales data of a code that does not exist in the product data file of the master machine, all of this cumulative sales data is collected at once. Since the other codes are aggregated, in order to perform sales analysis for each product, it is necessary to match the contents of the product data files of the master machine and each satellite machine.

However, if an unset product code is entered in its own product data file on a satellite machine, and product data such as unit price for this unset product code is added to the file by an emergency addition operation, the master machine's product data The contents of the file do not match. In such cases, the product data added at store opening is recognized, and the file contents are matched by, for example, operating the master machine after business hours and changing the product data files on the master machine and each satellite machine. .

[Problem to be solved by the invention] In this way, this kind of conventional master-satellite type P
In the OS system, the contents of the product data files of the master machine and each satellite machine may become inconsistent due to an emergency addition operation on the satellite machine, and in such cases,
For example, it was necessary to update the product data file of each satellite machine using the master machine after the end of the day, which resulted in poor operability.

Therefore, in the present invention, when an emergency product data addition operation is performed, the product data files of the master machine and each satellite machine are automatically updated, and the contents of the product data files of the master machine and each satellite machine can always be made to match. The aim is to provide a POS system that can improve operability.

[Means for Solving the Problems] The present invention stores product data files in which at least a unit price is set corresponding to each product code, and when a product code is input, calculates the corresponding unit price from the product data file. Read out sales data and register this sales data in the cumulative memory.Connect multiple cash register machines with an inline line, set one of them as the master machine, and store the sales data in the cumulative memory of each other satellite machine. A POS that collects registered cumulative sales data via the inline line.
In the system, each satellite machine queries the master machine for additional product data of this product code and unit price when an unset product code and unit price are input to the product data file after operating the emergency addition key and this emergency addition key. The master machine is equipped with additional product data inquiry means and a satellite file addition means for adding additional product data to its own product data file upon receiving additional product data from the master machine. A master file addition means that searches its own product data file when it receives a master file, and adds the additional product data to the product data file if it is not set, and a master file addition means that adds the product data added to the product data file by this addition means to each satellite machine. and additional product data transmission means for transmitting to.

In addition, each satellite machine uses an emergency addition key, and when an unset product code and unit price are entered manually in the product data file after operating this emergency addition key, the satellite machine queries the master machine for additional product data of this product code and unit price. a product data inquiry means; a first satellite file addition means for adding additional product data to its own product data file when an addition permission response is returned from the master machine in response to a data inquiry by the inquiry means; and second satellite file adding means for adding additional product data to its own product data file when receiving additional product data, and the master machine adds the additional product data to its own product data file when receiving an inquiry for additional product data from the satellite machine. A master file addition means that searches for and adds the additional product data to the product data file if it is not set and returns an addition permission response to the corresponding satellite machine, and the product added to the product data file by this addition means. It may also include additional product data transmission means for transmitting data to other satellite machines.

[How it works: With a POS system that takes such measures, when you enter a product code and unit price after operating the emergency addition key on the satellite machine, this product code and unit price will be queried as additional product data to the master machine. Ru. If the queried product data is not set in the product data file of the master machine, the product data is first added to the product data file of the master machine. In addition, the product data is sent from the master machine to each satellite machine,
Each satellite machine that receives this product data adds the received data to its own product data file.

In this way, product data input by an emergency addition operation on a certain satellite machine is automatically added to the product data files of the master machine and all satellite machines, and the contents of the product data files of the master machine and each satellite machine match. It will be done.

In another aspect of the invention, when a product code and unit price are input manually after operating the emergency addition key on the satellite machine, the product code and unit price are queried as additional product data to the master machine. Then, if the queried product data is not set in the product data file of the master machine, an addition permission response is returned to the satellite machine, and the additional product data is thereby added to the product data file of the satellite machine. The product data is also added to the product data file of the master machine. Furthermore, the product data is transmitted from the master machine to each of the other satellite machines, and each of the other satellite machines that have received this product data adds the received data to its own product data file. In this way, product data input by an emergency addition operation on a certain satellite machine is automatically added to the product data files of the master machine and all satellite machines, and the contents of the product data files of the master machine and each satellite machine match. It will be done.

FIG. 11 is a flowchart showing the key processing of the amount key 33, and the amount key 33
When input, the state of unit price input flag F3 is checked.

And if this flag F3 is set,
The PLLI code setting area of the PLU file 40 is searched based on the contents of the PLU code memory 47. Here, if a matching PLU code is found, an error message is displayed. On the other hand, if no matching PLU code is found, the version number, ID code, and PLU code stored in each memory 41, 43, 47, 48, 45,
The LU code, department code, and number data are read out, and additional PLU data is edited by setting the number data to +11 value.

Next, the Ni/S status in the status memory 42 is checked. Here, if the M/S status is "]", that is, the own aircraft is satellite a! 2. ~2n, the additional PLU data is sent to the master machine 1 via the inline line 3.
and wait for a response from master device 1. (Additional product data inquiry means) When an addition permission response is received from the master device 1, the additional PLU data is stored in the corresponding setting area of its own PLU file 40, and the version number in the version number memory 41 is increased by “+1”. Update. (First Satellite File Adding Means) Thereafter, the above-mentioned registration processing and display/printing processing are performed, the number buffer 45 is cleared, and the unit price input flag F3 is reset, and this key processing is ended.

On the other hand, when the M/S status is '0', that is, when the 5th machine is the master machine 1, the additional PLU data is stored in the corresponding setting area of its own PLU file 40, and the version number in the version number memory 41 is “＋
Update only 1″.

Next, the additional PLU data is sent to each satellite #12~2n via the inline line, and each satellite machine 21
Wait for response from ~2n. Then, if there is no response from any of the satellite machines that no addition is possible, the printer 18 is driven to print out a message indicating that the process has ended normally, and this key process ends. On the other hand, if there is a response indicating that addition is not possible, the ID code and additional FLU data of the satellite machine are printed out and this key processing is completed.

In addition, in the master [1, satellite machines 21 to 2n
The program is set to execute the process shown in FIG. 12 when there is an inquiry for additional PLU data from .

That is, when additional PLU data is received from the satellite devices 2, to 2n via the inline line 3, it is checked whether the version number in the data matches the version number in its own version number memory 41. If there is a mismatch, the satellite machine 2 that made the inquiry with the master ml. Since the contents of the single item files 40 of ~2o do not match, addition is not possible, and an addition not possible response is sent to the satellite machine to which the ID code in the received data has been set, and this process is completed.

On the other hand, if both version numbers match, the PLU code area of its own PLU file 40 is searched using the FLU code in the received data. If a matching PLU code is detected, it is incorrect data and cannot be added, and a response indicating that addition is not possible is sent to the ID in the received data.
Return t= to the satellite machine to which the code has been set, and end this process.

On the other hand, if a matching FLU code is not detected, the additional PLU code is stored in the corresponding setting area of the PLU file 40, and the version number in the version number memory 41 is updated by "+1". An addition permission response is returned to the satellite machine to which the ID code is set, and the satellite table 5
The version number corresponding to the ID code of 0 is “
Update only +1#. (Master file addition means) Next, transmit the additional PLU data to other satellite machines via the inline line 3 and wait for a response.
Additional product data transmitting means) When there is an additional re-response, the corresponding version number in the satellite table 50 is updated by '+1'. In this way, when additional re-responses are received from all other satellite machines, normal end printing is performed and this process is terminated. On the other hand, if there is a response that the addition is not possible, the ID code of the satellite machine and the additional FLU
Print out the data and finish this key processing.

Furthermore, each of the satellite machines 21 to 2o is programmed to execute the process shown in FIG. 13 when receiving additional PLU data from the master machine 1. That is, when additional PLU data is received from the master device 1 via the inline line 3, it is determined whether or not the received data can be added to the FLU file 40, and if there is no free area in the PLU file 4o or if the PLU file 4o is busy, Since the addition is not possible, an addition not possible response is sent to the master device 1, and this process ends.

If addition to the PLU file 40 is possible, the received additional PLU data is stored in the corresponding setting area of the PLU file 4o, and the version number in the version number memory 41 is updated by "+1". (Second satellite file Additional means) Next, send additional re-responses to master machine 1.
The printer 22 performs normal end printing, and this process ends.

In this embodiment with such a configuration, when the PLO code of a sales product is entered manually using the number key 31 and PLU key 32 on the keyboard 18 of the master machine 1 or each of the satellite machines 21 to 2n, the PLO code of the product to be sold is entered in RAM 1B. PL
U file 40 is searched. If the corresponding PLU code is set, the corresponding product name, unit price, etc. are read out, and the unit price is multiplied by the number of sales items in the multiplier memory 46 to calculate the sales amount. ) The cumulative sales amount is registered in the cumulative sales score area and cumulative sales amount area corresponding to the FLU code of the LU file 40, and the sales amount is added to the wealth counting machine 44. Further, the product name and sales amount are displayed on the display section 20 and printed on the receipt and journal by the printer 22. Note that the contents of the multiplier memory 46 are PLU
If a multiplier has been input using the numeric key 31 and multiplication key 34 on the keyboard 18 before inputting the code, the value will be that value, and if it has not been input manually, it will be "1".

On the other hand, by searching the PLU file 40, the corresponding PLU
If the code is not set, the display section 20 will display an error message. In this case, the operator of the master machine 1 or the satellite machines 21 to 2n operates the keyboard 18 to perform an emergency addition operation for unspecified products. That is,
After inputting the emergency addition key 38, the PLU code is input using the numeric key 31 and the PLU key 32, the department code is input using the department key 35, and the unit price is input using the numeric key 31 and the amount key 33. In addition, the number key 31 and the multiplication key 34
The amount of manpower required to determine the number of items sold is optional.

In this way, when the PLU code, department code, and unit price of unset products are input, if the 5 machines are satellite machines 21 to 20, the version number and ID code of the PLU file 40 are incorporated into the input data, and additional PLU data is edited. Then, an inquiry is made to the master machine 1 via the inline 4-wire 3.

The master machine 1 that received the inquiry for the additional PLU data searches the PLU file 40 and, when it is confirmed that the product is not set, returns an addition permission response to the satellite machine that made the inquiry, and This additional PLO data is added to the PLU file 40 in machine 1. Further, additional PLO data is transmitted to other satellite machines via the inline line 3.

The satellite machine that has received the addition permission response adds the edited additional PLO data to its own PLU file 40. Then, the registration process for this urgently added product is executed.

On the other hand, other satellite machines that have received the additional PLU data from the master machine 1 add the received additional PLU data to their own PLU files 40.

In this way, according to this embodiment, when an emergency addition operation is performed on a certain satellite machine, the product data of the emergency addition product is not only stored in the PLU file of the master machine 1, but also in the PLU file of the master machine 1.
It is automatically added to the PLU files of all satellite machines 21 to 2n. Therefore, even if there is an emergency additional operation on a satellite machine, the master machine 1 and each satellite machine 2 are always connected.
．． -20 PLU files 40 are matched in content. Therefore, as in the past, for example, after the work is finished, the master machine 1
Each satellite machine using 2. There is no need to perform the PLU file update operation of ~2o, and operability can be improved.

Furthermore, even if an emergency addition operation is performed on the master machine 1, the additional FLU data will be transferred to the PL of the master machine 1.
In addition to being added to the U file, each satellite machine 21~
2n and added to the PLU file, so master machine 1 and each satellite machine 2□~2o
The contents of the PLU files 40 are matched.

Note that the present invention is not limited to the above embodiments.

Other embodiments of the present invention will be described below.

In this other embodiment, if the PLU code input in the satellite machines 21 to 2N is not set in the PLU file 40, the PLU code is added to the master machine 1 by an emergency passage operation.
This embodiment is similar to the previous embodiment in that LU data is transmitted and this additional PLU data is added to the PLU file of the master device 1.

However, from master machine 1 to all satellite machines 2I to 2
Additional PLU data is transmitted to N, and each satellite machine 21 to 22N receives i[l[P
The difference is that data is added to the own PLU file 40 depending on the LU data. Of course, even with such a configuration, the same effects as in the embodiment described above can be achieved.

[Effects of the Invention] As detailed above, according to the present invention, when an emergency product data addition operation is performed, the product data files of the master machine and each satellite machine are automatically updated, and the master machine and each satellite machine are always It is possible to provide a POS system that can match the contents of product data files of satellite machines and improve operability.
